Installation Precautions
Before installing the optional hardware, make sure you
have a Phillips screwdriver and ample space to work.
Protective cushions or supports for the instrument may also
be needed.
Before beginning installation, switch off the power to the
instrument and connected peripherals, and unplug them from
the power outlet. Then remove all cables connecting the
instrument to other devices. (Leaving the power cord connected
while working can result in electric shock. Leaving other cables
connected can interfere with work.) Installation or removal of any
devices should be started ONLY after the instrument (and the
optional hardware) returns to normal room temperature.
Be careful not to drop any screws inside the instrument during
installation (this can be prevented by keeping the optional units
and cover away from the instrument while attaching). If this does
happen, be sure to remove the screw(s) from inside the unit
before turning the power on. Loose screws inside the instrument
can cause improper operation or serious damage. If you are
unable to retrieve a dropped screw, consult your Yamaha dealer
for advice.
Install the optional units carefully as described in the procedure
below. Improper installation can cause shorts which may result
in irreparable damage and pose a fire hazard.
Do not disassemble, modify, or apply excessive force to board
areas and connectors on optional units. Bending or tampering
with boards and connectors may lead to electric shock, fire, or
equipment failures.
Before handling the optional units, you should briefly touch the
metal surface to which the optional unit cover is attached (or
other such metallic area/be careful of any sharp edges) with your
bare hand so as to drain off any static charge from your body.
Note that even a slight amount of electrostatic discharge may
cause damage to these components.
It is recommended that you wear gloves to protect your hands
from metallic projections on optional units and other
components. Touching leads or connectors with bare hands may
cause finger cuts, and may also result in poor electrical contact
or electrostatic damage.
Handle the optional units with care. Dropping or subjecting them
to any kind of shock may cause damage or result in a
malfunction.
Be careful of static electricity. Static electricity discharge can
damage the IC chips on the Plug-in board. Before you handle the
optional Plug-in board, to reduce the possibility of static
electricity, touch the metal parts other than the painted area or a
ground wire on the devices that are grounded.
Do not touch the exposed metal parts in the circuit board.
Touching these parts may result in a faulty contact.
When moving a cable, be careful not to let it catch on the circuit
Plug-in board. Forcing the cable in anyway may cut the cable,
cause damage, or result in a malfunction.
Be careful not to misplace any of the screws since all of them are
used.
Do not use any screws other than what are installed on the
instrument.
